function WebGrid1_OnAfterResponseProcess(controlId, actionName, lastRequestObject, xmlResponseObject) {    var WebGrid1 = ISGetObject(controlId);
    if (actionName == "DeleteRow") {
        var childRowsLenght = lastRequestObject.GetParentRow().GetChildRows().length;
        // if there is no child row any more
        if (childRowsLenght == 0) {
            // we need to refresh the WebGrid to apply the ChildRowEmptyAction property
            WebGrid1.Refresh();
        }
    }
    return true;
}

Also “RestoreExpandedChildRows” property to “True” and “RestoreRowSelection” to “All”.

Hope this helps.

Hello,

Could you please provide me a simple sample that replicate your issue?
So I can help you to investigate your issue on my end.

Thank you.

Hi Kristian ,

This is my samples,please have a look! Thank you.

Hello,

Thank you for your sample.

After I investigated you code, it seems the issue persist due to mistakenness in your code.
You already define the WebGrid’s structure from the beginning you create the WebGrid.
Therefore, you couldn’t delete the structure just by using this code:

WebGrid1.LayoutSettings.Hierarchical = false;WebGrid1.ClientAction.RefreshModifiedControls();

And as far I know, you couldn’t delete table by using this query code:

string StrSql = "Delete from Schedules ";

However, if want to make any changes in your WebGrid’s structure.
I recommend you to create the WebGrid’s structure programmatically.
With this scenario, you could have more dynamic WebGrid’s structure.

Hans.
